sroor. FOR AXMINSTER LOOMS.

Application filed July 5, 1927.

This invention relates to improvements in spools particularly those usedon the carrier chains of Axminster looms and it is the general object of the invention to provide a spool having a barrel and a flange or head so held to the barrel as toprevent relative angular movement of these parts.

Axminster looms operate with a large number of tube frames which are presented one at a time to the fabric. The tube frames carry spools on which are wound variously colored yarns arranged in a pre determined order according to the pattern. When yarns are being wound on the spools the latter are placed in a winding machine and rotated to draw the yarns from a creel by having the spool head engaged by a drivs ing clutch. Each yarnris under tension and in a 27 inch spool there will ordinarily be 189 warpthreads so that the strain of rotating the barrel is considerable. This strain must be transmitted through the connection between the head and the spool barrel and as heretofore constructed this strain has been taken in part by lugs which enter a slot in the barreland in part by tangs extending from the body of the head into the end of the barrel. method of preventing relative rotary movement between the head of the barrel will operate'sufliciently well for mill conditions yet the construction is not free from faults and it is an important object of my present invention to form the head and end of the barrel with complementary mutually engaging portions which will positively prevent relative rotary movement of the barrel and the head. As shown herein I form corrugations on the head which enter grooves extending across the. end of the barrel.

Before the winding operation can be started it is necessary to provide some means for holding the yarns to the barrel and this is usually done by a rod lying in a slot extending lengthwise of the barrel. This rodmust of course pass through the head and when the latter is formed of steel it has usually been made as set forth in patent to Hutchins No. 1,067,656 with small lugs lying on each side of the opening for the rod which extend into the slot in the barrel. In this way the lugs position the opening to guide the rod into its proper position. It is a further object of my present inven- It has been found that while this- Serial No. 203,446.

ing of the lugs with respect to the slot in the barrel.

With these and other objects in view which will appear as the description proceeds, my invention resides in the combination and arrangement of parts hereinafter described and set forth in the claims.

As shown herein the spools are provided with two forms of heads one indicated-at 10 as having a relatively broad rim to cooperate with a friction device on the tube frame indicated at F and the other head'indicated at 11 having a narrow rim and being adjacent one of the center bearings C. My inventionrelates to the con- 'struction of either form of head. Ordinarily there will be only two heads of the form indicated at 10, namely those which are at 7 lny inventioii. is l i The spool is provided with a 1barrel20 21 and sai PElI Of ears 25 from the body: 22 in a direction to extend into the slot 21 and said the ends ofthe tube frames to cooperate with i spoo'lunay be madetheisameor each spool may be provided with but one head made according to my present invention and as the ends oi'the spools may be the same a description of one will besuflicient to set forth made preferably though not necessarily of wood and having a'slot 2l extending therealong to-rec'eive a yarn end retaining rod not shown but proportioned to clamp the variously colored threads from the freel in the groove 21.

As previouslystated my present invention relates to improved means iori preventing:

angular moyement between the head and the barrel-especially when the yarnsare being wound on the spool. In carrying my present' invention into effect I provide the end i of thebarrelwith a numberotpreferably parallel grooves 40 certain ofsaid grooves as indicated;particularly at 41' extending in line with the ed es of, the slot 21 and being spaced apart a istance substantially equal to the distance between the ears 25. The bod ortion 22 of the head is provided witlle ongated wrrugationsdepm ortion'ed to fit snugly intotlie grooves 40 an 41. Cermm of these i corrugations as indicated at 43 are in alignment withthe ears 25 while the other lugs are proportioned and spaced so as to enter the grooves on the end of the spool barrel. As shown in Fig; '4 I fin d it desirable not to extend the corrugations 43" up tothe ears 25 inasmuch as to doso might cause the die which produces the eorr'ugaa tions to weaken that part of the metal of openin 24 .proper1yaligned with theslot 21;

The b0 t27' niaythenxbe ssed thr'ough the opening 26sand into a ho e previously bored t rough the barrel so that saidboltmay be threaded through the nut 32 j'Wlhh thehead tight against the body ofthe barrel soas to 5 hold the corrugations*inithe'grooves on the end of the :barrel. .In this way angular movement between the head and barrel is effectively preventeidw i From the" foregoing itgwill be seen 1 that i I my have=provided a very simplesnieans'forhold j ing the head ofian 'Axininster' spool to the barrel and that theears whieh serve to align the opening 24in] the head with the slot 21 in the' barrel are" p I slots across the end of the barrel. {Althoughlrhave shown theeorrugations onthe head as: being confinedsubstantiallyywithin a aircle oi the same diameterz'asthatof the'barrel yet Iddjiot wish'to limiteato this con mstructionvas the invention will'be' equally effective irrespective either length of the corrugations on! the provided they are of "sufficient; lengthito ave proper*-'hold-' ring engagemenflwith theUgrooves in than;

1. In an Axminster loom spool having a barrel with a longitudinal slot therein, a head having an opening to register with the slot, and interengaging grooves and coring"- tions on the barrel and head, respectively, ears extending from the head on opposite sides of the opening and located to align with certain of the grooves in the barrel to be guided with respect to the slot so that one ear lies on each side of the slot.

2. In an Axminster loom spool having a barrel the periphery of which has a longit-udinal slot therein, means defining grooves extending across the end of the barrel, a head having an opening therein to register with the slot,ears formed on the head and lying on each side of the opening in the head, and corrugations formed on the head to enter the grooves in the end of the barrel, the ears aligning with certain of the grooves to be guided with respect to the slot so that one ear will lie on each side of the slot.

3. In an Axminster loom spool having a barrel with a longitudinal slot therein, the

end of the barrel having a plurality of parallel grooves formed therein extending sub stantially parallel to the side walls of the slot in the barrel, a head for the spool, projections extending from said head and ar-- ranged to enter the grooves in the barrel, ears on the head parallel to the projections and ali ning with certain of the grooves, said head having an opening between the ears which is held in alignment with the slot in the barrel by the ears and projections as they enter the slot and grooves respect-ively. v

4:. A spool barrel to form part of an AX- ininster loom spool, said barrel having a slot extending longitudinally therein with sub stantially parallel side walls, the end of the barrel having a plurality of parallel grooves extending thereacross and which are parallel to the side walls of the slots and certain of which register with the side walls of the slot to guide ears carried by a spool head.

, In testimony whereof I have hereunto affixed my signature.
